White Si-O-C(-H) Particles with Photoluminescence Synthesized by Decarbonization Reaction on Polymer Precursor in a Hydrogen Atmosphere

Colorless white Si-O-C(-H) particles with photoluminescence were synthesized from silicone resin precursor. Pyrolysis of the precursor particles in a hydrogen atmosphere was effective for adjustment of resulting carbon content. Analysis of chemical compositions revealed that the resulting materials contained a small amount of hydrogen with Si, O, and C.
